Abstract

The invention discloses a stirring type sewage treatment device. The stirring type sewage treatment device comprises a shell of barrel structure, a sewage inlet pipe and a water outlet pipe are arranged at the top and the bottom of the shell respectively, a water quality testing pipe is arranged at the bottom of the shell, several filter screens are arranged in the shell at equal distance and are of inverted-cone structure, the shell is divided into a left shell and a right shell which are hinged, and a connecting and fixing device is arranged between the left shell and the right shell. A rotary motor is arranged at the top of the shell, and a rotary shaft of the rotary motor is vertically and downwardly arranged and penetrates the filter screens. The rotary shaft is provided with stirring blades between the filter screens, the filter screens are of detachable structure so as to be conveniently cleaned and effect and efficiency of sewage treatment are ensured.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sewage treatment device. Background technique [0002] At present, with the improvement of people's life, there are more and more mechanized products, and the environmental pollution is becoming more and more serious; at present, industrial wastewater is often produced in mechanical production, and these industrial wastewater often contain a large amount of heavy metal solid particles. The discharge of similar industrial wastewater will cause more and more serious pollution to the living environment of human beings; at present, the device for solid-liquid separation in industry generally adopts the sedimentation method, but this method has the following disadvantages: 1) Not only does the solid-liquid separation not Clean, and the separation efficiency is low, 2) After long-term use, scale will be generated in the housing of the solid-liquid separation device, ...

[0002] At present, with the improvement of people's life, there are more and more mechanized products, and the environmental pollution is becoming more and more serious; at present, industrial wastewater is often produced in mechanical production, and these industrial wastewater often contain a large amount of heavy metal solid particles. The discharge of similar industrial wastewater will cause more and more serious pollution to the living environment of human beings; at present, the device for solid-liquid separation in industry generally adopts the sedimentation method, but this method has the following disadvantages: 1) Not only does the solid-liquid separation not Clean, and the separation efficiency is low. 2) After long-term use, scale will be generated in the shell of the solid-liquid separation device, which is difficult to clean

[0006] For another example, the Chinese patent document with the notification number CN 203999081 discloses a stirring coagulation device for sewage treatment, including a stirring tank, the mixing tank is equipped with a flow guiding cylinder with a mixing chamber and a rapid stirring tank located in the mixing chamber. Assemblies, the upper part of the diversion cylinder is provided with the sewage inlet pipe and the dosing pipe connected with the mixing chamber, the bottom of the mixing chamber is connected with the inner cavity of the mixing tank, and the mixing tank is also equipped with a slow speed pipe located below the diversion cylinder. Stirring component, the device only plays the role of stirring, it cannot filter and treat sewage, and its function is relatively simple
